JAKARTA, Indonesia — A U.S.-born male Sumatran rhino arrived in his ancestral home of Indonesia Sunday, making the long journey from Cincinnati on a mission to mate to help save his critically endangered species from extinction.

The 8-year-old rhino, Harapan, was born at Cincinnati’s zoo and spent nearly the past two years as the last Sumatran rhino in the Western Hemisphere.

He arrived at Jakarta’s Soekarno-Hatta airport Sunday in a special travel crate aboard a Cathay Pacific jet.

Conservationists hope Harapan can mate with one or more of the three females at Way Kambas, where Ratu, a 12-year-old female rhino born in the wild, is now pregnant with her second calf and is expected to give birth in May.
